To all whom it may concern: 1

Be it known that I, MA'rrHnw MAYER, a citizen of the United States, Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Bowden Controlling Mechanisms, of which the following is a specification.

My invention relates to Bowden controlling mechanisms, and particularly controlling mechanisms adaptable for use in connection with a shut-oil valve installed in the supply line for gasoline to an automo' bile engine, although obviously, it is not limited to such a use.

An object of my invention is to produce such a mechanism operable .by a simple Bush and pull. Bowden wire with a suita le controlling handle therefor, and which will, when set to either extreme position, re main in such a position regardless of the vibrations of the vehicle.

Another object is to rovide such a mechanism which will bev positive in operation and which by its characteristic designing, in-

dicates to the operator while being operated the position of the valve controlled thereby.

Other objects of my invention and the in- .vention itself will drawings forming a part of this specification.

Referring now to the drawings Fig. 1 shows a side elevation of an em-- bodiment of my invention, the manuallyoperable portion being shown in isometric vlew,

however, the apparatus being shown in one of the valve extreme positions.

Fig. 2 is a view similar to that of Fig. 1 but with the valve in an intermediate posi-' tion.

Fig. 3 is a similar view but with the valve in the other extreme position.

Fig. 4 is a top plan view of the valve and adjacent controlling ap aratus with the valve shown in interme iate osition, the

other extreme positions being, owever, in-

dicated by dotted lines.

Referring now to the. figures in all of which like parts are designated by like reference characters, at 1 I show the casing of a valve interposed in a gasoline feed pipe line 2 leading from a source of gasoline supply such as a vacuum storage tank to a point of gasoline consumption such as the engin of the automobile.

At 3 I show a valve handle having its upresiding at be apparent from the 1924. Serial No. 710,887.

er portion bent at right an les as shown at At 5 I show the casing o? a Bowden wire fiontrol which is tubular and receives a Bowen wire 6. attached at one end to an operating handle 7 and at the other end the Bowden wire 6 is bent downwardly at right angles and passes through a perforation 8 1n the valve handle portion 1 and is headed over at v9 to prevent removal therefrom,--the fit of the wire 6 in the opening 8-being loose so as to ermit relative rotation of the wire within-t 1e opening. At 10, I show a Bow-' den wire support secured at 11 on an extension 12 of the casing 1, said extension being a portion of the gasoline line 2.

At 13 I provide a flexible Bowden wire directing and protecting tube-secured at one end by a clamping nut 1 to the end of the tubular frame 5 and at the other end being secured within an end openingtherefor in the support as shown at 15, the Bowden wire 6 passing from the point 8 on the valve handle 1 to the-attached handle 7 passing throu h the support 10, the flexible tube 13 and the tubular frame 5, the tubular frame 5 carrying a flange 16 by which it is secured to a support such as the dash of an automobile 17.

As shown herein the above is accomplished by means of screws 18. 1 The opening through the support 10 is reduced in diameterat the end 19 towards'the-valve handle 4, and the valveoperating element 3 is adapted to rotate within the casing 1, as illustrated, on a vertical axis to permit the fiow of gasoline as shown preferably at Fig. 1, and to shut ofi the flow of gasoline completely as shown preferably at Fig. 3. 2 does not illustrate an operative position,

but only aposition intermediate the two extreme positions and which extreme positions ma be reversed as to their functions.

y referring nowparticularly to Fig. 4:, it will be seen that when the valve is in its intermediate position, the Bowden'wire 6-, which is of spring material such as steel wire. is bent rather abruptly at the position 20 where it enters the support 10, but that in the two extreme positions shown in dotted lines in Fig. 4, and as illustrated in Fi s. 1 and 3, aswell, it will be noted that t e Bowden wire is approximately straight and in axialali nment with the main portion of the Bow en wire extendin between the yalye and the handle 7, an partieular'li s m axial alignment, appro y, wi

ill

the opening through the support 10 at its forward portion 19. By this arrangement, the operator will not leave the controlling handle 7 in an intermediate position, since by the resistance to his push or pull eflort in advancing or retracting the handle 7, which is noticeable when the valve is near the intermediate position and the sudden release'of resistance at either end of the movement, the different positions .of the valve will be communicated to him. Moreover, this arrangement causes the valve to snap into either extreme position suddenly by the sudden release of resistance to the adjusting efforts of the operator.

Having thus described a particular embodiment of my inventioml am aware that numerous and extensive departures may be made therefrom but without departing from the spirit of my invention.

I claim Z.- i

1. In a valve adjusting mechanism having an extreme position and other positions, the combination with a Bowden wire for operating the valve, a valve handle for the valve and adapted to rotate the same to different operative positions, a handle for the Bowden wire, a protecting and directing tube enclosing said wire, the end of said tube being held approximately rigid with respect to the valve and its opening being approximately in axial alignment with the point of connection of the said wire to the said handle when the handle is in its said extreme position, and out of alignment therefrom when the handle is in other positions.

the end of said tube being held approximate 1y rigid with respect to the valve and its opening being approximately in axial alignment with the pomt of connection of the wire to the handle when the handle is in either its valve opening or valve closing positions, and out of alignment therefrom when the handle is in other positions.

In testimony whereof I hereunto affix my signature this 22 day of April, 1924.
